铸造用阿尔法淀粉
该产品使用优质食用级淀粉采用先进生产工艺加工而成，具有粘结力高、分散性好、完全无毒环保的特点。是球团铸造、混砂铸造和石膏板生产的优良粘合剂，能够较大地改善铸造模型的湿性能以及干强度，提高铸件模型的表面光洁度，是铸造业不可缺少的粘合助剂。 1、 本产品在铸造工业中抗粘砂作用明显，不会形成亮碳。防止粘砂缺陷和降低表面粗糙度。 2、 提高型砂的拉强度，砂型表面产生的孔隙，可以减少硅砂受热膨胀，提高抗夹砂能力。 3、 降低型砂对水份的敏感性，减少水份和提高紧实率，易于造型，使型砂的高温度降低。 4、 提高砂型抗风干能力，减少铸件中冲沙缺陷，降低砂与模具的摩擦阻力，减少起模不良出现的废率，提高成品率。 本产品采用25kg/袋包装，使用白袋子加内衬包装，在保存过程中注意防潮，保质期为18个月。 建议加量为0.5%～1.5%，具体加量由厂家视具体情况而定。

阿尔法淀粉，具有粘结力高、分散性好、完全无毒环保的特点。是球团铸造、混砂铸造和石膏板生产的优良粘合剂，能够较大地改善铸造模型的湿性能以及干强度，提高铸件模型的表面光洁度，是铸造业不可缺少的粘合助剂。
1、能够提高型砂的热湿拉强度外、砂型表面的a淀粉受热燃烧后产生空隙，可以缓冲硅砂受热膨胀。从而大大提高型砂的抗夹砂能力。　
2、能够降低型砂与模样之间的磨差阻力，提高型砂的起模性，减少由于起模不良而出现的型废率。
3、如果湿砂型在合型以前放置一段时间，型砂表面失水而致表面强度下降和*磨损，浇注金属液时易被冲蚀。放置时间较长或者天气较干燥时，问题更为严重。型砂中加入a淀粉可以提高型砂的抗风干能力，减少铸件冲砂缺陷。
4、淀粉能够显著降低型砂对水份的敏感性，并能减少型砂的含水量和提高型砂的坚实率。混砂时如果型砂的含水量较低，更回显得相当干散和硬脆。向型砂中加入少量本品，型砂立即变的柔韧，易于造型使用。使用a化度较高的a淀粉是效果会更加明显。
5、使型砂的高温强度降低，因而改善型砂的落砂性能。
二、产品指标
水分 8％
糊化度 ≥96%
灰份 ≤0.5％
粒度(80目通过） ≥95%
三、使用说明

A drilling-mud additive used to control fluid loss in water muds ranging from freshwater to saturated-salt to high-pH lime muds. Starches have thermal stability to about 250°F [121°C]. They are subject to bacterial attack unless protected by high salinity or bactericide. Drilling-grade natural starch has API/ISO specifications for quality. Starches are carbohydrates of a general formula (C6H10O5)n and are derived from corn, wheat, oats, rice, potatoes, yucca and similar plants and vegetables. They consist of about 27% linear polymer (amylose) and about 73% branched polymer (amylopectin). The two polymers are intertwined within starch granules. Granules are insoluble in cold water, but soaking in hot water or under steam pressure ruptures their covering and the polymers hydrate into a colloidal suspension. This product is a pregelatinized starch and has been used in muds for many years. Amylose and amylopectin are nonionic polymers that do not interact with electrolytes. Derivatized starches, such as hydroxypropyl and carboxymethyl starches, are used in drill-in fluids, completion fluids and various brine systems as well as in drilling-mud systems. The use of starch typically causes a minimal increase in viscosity while effectively controlling fluid loss.
